Use Dalton's atomic theory to explain what is happening to the carbon atoms when a diamond is burned and to oxygen and hydrogen atoms when water is electrolyzed.
Draw the structure for the molecule that fits the following description and then name it according to IUPAC formalism.
Discuss the importance of valence electrons in this lesson. What and where are they? Why are they important? Be sure to base your answer on what we discussed in THIS class and use the terminology from the course materials.
